I know it is a good idea for duplicate pages, blog tags, etc. but I remember somewhere that you can help the overall link juice of a website by adding no index no follow or no index follow low quality content pages of your website. Is it still a good idea to do this or was it never a good idea to begin with? Michael

I have a client who is using a SEO company (Hubshout, delete name if necessary) to boost traffic to their website. They are doing this by publishing articles and submitting them to article directories, then they use their own sites/blogs (which are valueless, PR and MozRank of zero) to point to these articles and they say that this helps boost there rankings. How? They are not linking to the clients websites, creating artificial links from their own websites to article directories instead of the clients website. Are they trying to boost the value of the article or trying to boost their own websites? How does this help out the client? It is similar to three way linking but is not.
